 Jiangsu Haifa · API610 Series OH2 Chemical Process Pump

 Product Overview: The "Safety Guardian" in Heavy-Duty Process Centers

Jiangsu Haifa Machinery Manufacturing Co., Ltd. introduces its API610 Series OH2 Single-Stage Overhung Chemical Process Pump, a heavy-duty centrifugal pump strictly designed according to the latest version of the American Petroleum Institute API610 (ISO 13709) standard.

This product belongs to the OH2 configuration (centerline support, radially split, overhung). Targeting harsh operating conditions in petrochemical, coal chemical, and power industries, Haifa OH2 pump has been systematically optimized in terms of high-temperature resistance, high-pressure resistance, long service life, and stability. It aims to replace imported high-end products, providing a safe, stable, and efficient fluid handling solution for continuous industrial production.



 Core Advantages: Why Choose Haifa OH2?

 1. Rigorous Design Meeting International Standards
 Design Standard: Fully complies with API610 11th/12th editions, with API Q1 quality system certification basis.
 Heavy-Duty Design: Bearing life L10 exceeds 25,000 hours, far surpassing standard industrial pump requirements, ensuring trouble-free operation under continuous duty cycles.

 2. Centerline Support Designed for High Temperatures
 Thermal Stability: Pump casing adopts centerline support structure. When conveying media up to 450°C, the pump casing expands uniformly, the shaft centerline remains unchanged, effectively preventing coupling misalignment and seizure caused by thermal deformation, ensuring high-temperature operational reliability.

 3. Highly Reliable Rotor System
 Rigid Shaft Design: Uses large-diameter, short-span rigid shaft design. Shaft deflection is far below the limit allowed by API610 (typically <0.05mm).
 Advanced Balancing Technology: Impeller features front and rear wear rings and balance holes to precisely balance axial thrust; paired with back-to-back mounted angular contact ball bearings, significantly enhancing rotor stability.

 4. Flexible Sealing Arrangements
 API682 Seal Chamber: Seal chamber dimensions fully comply with API682, compatible with cartridge single, double, and tandem mechanical seals.
 Support Systems: Can be configured with full API flushing plans such as Plan21, Plan52, Plan53 according to operating conditions, easily handling flammable, explosive, toxic, or particle-laden media.

 Applications: Designed for Harsh Conditions

Haifa OH2 chemical process pumps are widely used in continuous, high-risk industrial processes, making them an ideal replacement for imported pumps:

 Oil & Gas: Atmospheric/vacuum tower bottom pumps, reflux pumps, light hydrocarbon transfer, crude oil pipeline pressurization.
 Petrochemicals: Catalytic cracking, hydrotreating, aromatics units, polypropylene/polyethylene units.
 Coal Chemical Industry: Methanol units, dimethyl ether units, ethylene glycol transfer, coal slurry transfer (with wear-resistant materials).
 General Industry: Power plant boiler feedwater, high-pressure reverse osmosis feedwater for desalination, pulp & paper.



 Design & Manufacturing Highlights

 Modular Design: Bearing and seal components are interchangeable across different sizes, greatly reducing spare parts inventory and maintenance costs.
 Rugged Baseplate: Provides heavy-duty baseplate meeting ISO 13709 2x nozzle load capability, allowing precise alignment without grouting (optional), easy installation.
 Condition Monitoring: Bearing housing预留 connections for thermometers and vibration monitoring, supports DCS integration for unattended intelligent monitoring.
